Re: How to improve SmackDown!?
1. During his initial run in WWE, Brock Lesnar was exclusively a Smackdown star. At some point he needs to make a return to Smackdown, I think; it would be great for him to actually wrestle a match on Smackdown; maybe against Randy Orton? It would be easy to book. Have the fans vote for the "Greatest Superstar In Smackdown History", rig the vote so that Randy Orton wins and then, as he comes to collect his award, Brock Lesnar could appear and beat the shit out of him. Book a match between them for the crown of "Smackdown's Greatest Star".
2. After Lesnar returns to Smackdown, book a decent feud between him and Wade Barrett. Build Barrett up as a tough as nails old fighter (specializing in Street Fights) and then book Lesnar vs Barrett in a genuine MMA cage fight at a PPV (kind of like Ken Shamrock's Lion's Den).
3. I'd like to see a long running fued between Wade Barrett and Sheamus, as well, with Barrett going over as the tough old heel. If they really invested some time and effort in Wade Barrett, they could have a really unique main event draw. Then, build towards a Wade Barrett vs Undertaker feud. If Undertaker's really on his way out, use him to properly put over one last great star.
4. Put Paul Heyman back in charge of the show. As GM he would be great. He could share the role with Booker T, leading to a power struggle, and then finally take over complete control. It would be sweet to see Heyman large and in charge again.
5. Build a stable around Dolph Ziggler. Get Ric Flair and Bobby Heenan to coach and manage him, and build him up as an arrogant main event heel. Building Ryback simultaneously as the top face would get people excited/
